GRABOT-GIN SYSTEM.

SPECIFICATION forming part of Letters Patent No. 731,855, dated June 23, 1903. Application filed July 28, 1902. Serial No. 117.296. KN model-l which the following is a specification.

y invention relates: to certain new and useful improvements in grabot-gin systems, which systems are especially designed for treating lumpy cotton or grabots and the bolls as they come from the ordinary gins to save as much of the lint which would otherwise go to waste and to remove any remaining lint from the seed. My system is designed to antomatically eifect these purposes and to effectually separate and handle the seed and bolls after they have passed through the grabot, so as to minimize the loss of seed as much as possible.

The objects of my invention'are, as above stated, to mechanically handle the seed, bolls, and grabots to the grabot-gins and to take the seed and bolls from these latter and separate and dispose of them with a single fan, I carry out these objects as will be more fully hereinafter set forth in the specification, d rawings, and claims.

In the drawings, Figure 1 is a sectionalelevation of thegin-house and one side of the boiler or fuel room, showing generally a'side elevation of the devices used in my system. Fig. 2 is a detail section showing the end of the shaker, which will be hereinfter more fully referred to, and of the discharge-spouts. Fig. 3 is a plan view of the shaker, the discharge-spouts, and the feed-hopper. Fig. 4 is a plan view showing arrangement of the fan and piping to and from same.

Referringnow to the drawings, in which like numerals indicate the same or like parts in all the views, 1 is a boll-screen from which n the overflow-seed, with lint attached, the grabots, and the bolls drop into ahopper 2, from which they are conveyed by suction through the pipe 3 to the automatic discharge-valve or separator 4:. n

5 is a discharge-pocket, having a door 6, which will open, as shown by the dotted line 6, when struck by any heavy foreign substance, such" as a pebble, which have been carried up with the bolls and grabots.

In the separator 4 the bolls and grabots are separated from the conveying air and are dropped out into the grabot-room 7, in which room they may be stored, if, as is generally the case, it is so desired. From this room they are fed through a chute 8 into the grabot-gin 9, and there are effectually torn to pieces and all possible lint removed from the seed, which lint passes out at the back end of the gin over a slow-speed condenser 10 and is collected by same into a vat suitable for baling. The seed and bolls drop through the spout 11 to a shaker 12. This shaker has a screen-bottom 13, extending, as will beseen by reference to Fig. 2, to the lower end of same and a solid bot-tom l4. Seed and bolls dropping on this shaker are separated, the seed dropping through the screen 13 and being carried by the bottom 14 to the lower end of the table, where they drop .into the spout 15. The bolls being too large to pass through the meshes of the screen pass over the lower end of same and drop into the spout 16. The seed and bolls are carried by their respective spouts 15 and 16 to the feeder 17, which is divided (see Figs. 3 and 4) into two compartments 1S and 19,

'which'respectively receive the seed and bolls and feed them into the conveyor-tubes 20 and 21, which lead to the seed-room and the fuelheap, respectively. These tubes are furnished with airby a fan 22, which is connected by a suction-tube 23 with the separator 4. 24 is a cylinder into which the bolls are blown tangentially at one side, so that they follow the inside of the cylinder until their speed is checked, so that they may drop straight to the ground. Itwill be seen that by my sys tem I secure the suction and'a double discharge-pipe from a single fan and that I separate and recover the seed from the grabot-gin as well as from theregular gin." I have not illustrated the details of the mechanism herein described, as the machines used are of standard types and the system only is involved;

It will of course be evident that should it not be desired to re-treat the cotton and seed this system may be utilized in a direct wagonto-gin system with the single substitution of an ordinary gin for a grabot-gin.

Having fully described my invention, What I claim, and desire to secure by Letters Patent of the United States, is

1. In a grabot-gin system, the combination with the gin, a suction-pipe, a feed-hopper thereon, an automatic trap for foreign substances and a separator discharging to said gin, of a shaking-table, parallel spouts beneath the discharge end of said table, a feeder divided into two compartments, one beneath each of said spouts, parallel conveyer-tubes below said compartments, and a single fan blowing air through said tubes, substantially as shown and described.
